Abstract

The utility model provides a harrow capable of being used by being pushed and pulled forwards and backwards, wherein, triangular support blocks are fixed at the front end of a harrow handle; two U-shaped groove support frames are uniformly arranged on a harrowing plate; the triangular support blocks are in hinge connection with the support frames and take the shape of equiangular triangles of which the vertex angles are 30 degrees; and a clearance of 0.2 to 1.0 cm is kept between the bottom edges of the triangular support blocks and the bottoms of the U-shaped grooves of the support frames. According to the utility model, the harrow handle and the harrowing plate are connected through the triangular support blocks and the support frames which are in hinge connection, and the upwards turning clearance is kept in order that an included angle of inclined forces is generated, so that no matter the harrowing plate harrows soil forwards or backwards, transmission of force can be performed smoothly, adjustment of angles can be realized, conversion of a conventional action with unidirectional useful work into an action with bidirectional useful work can be realized, and convenience is provided for small-scale land leveling. The utility model has a simple and flexible structure, and is convenient to use, time-saving and labor-saving.

Description

Can before and after the rake of raking the soil level that uses of bi-directional push-pull

Technical field

The utility model is the improvement to the existing rake structure of raking the soil level, especially provide a kind of can before and after the rake of raking the soil level that uses of bi-directional push-pull, belong to the farm machinery technical field of tools.

Background technology

The existing rake of raking the soil level comprises the plate of raking the soil level, button and handle, and its main points are that button is a kind of pipe, and this pipe is centered close on the rake body symmetrical center line, and its lower end is annular with the affixed graft union of rake body.The active force that handle is applied on the rake body evenly disperses through rake body symmetrical center line again, and the rake function singleness is used inconvenient; Can only be independent the pushing away forward or past post-tensioning of mud; More time and strength are consumed in to lift to send and rake the soil level, and increase labour intensity, reduce efficiency.

Summary of the invention

The utility model provide a kind of can before and after the rake of raking the soil level that uses of bi-directional push-pull, having solved existing raking the soil level can only unidirectionally use, can not before and after the problem of pushing-pulling bi-directional use.

The technical solution of the utility model is following:

Comprise rabble arm, the plate of raking the soil level; It is characterized in that: the front end at rabble arm is fixed with the triangular support piece; Two the U type groove bracing frames that evenly distribute on the plate of raking the soil level, the triangular support piece is connected with the bracing frame hinge, and the triangular support piece is an equiangular triangle; Drift angle is 30 degree, and the U type bottom land of the base of triangular support piece and bracing frame leaves the gap of 0.2 ~ 1.0cm.

Use the utility model forward buck rake ground the time, the upper limb on triangular support piece base can be against on the plate of raking the soil level through the U type bottom land of bracing frame, makes the plate of raking the soil level become certain included angle with level, can push the mud that protrudes to front; In like manner, in the time of toward post-tensioning, the lower edge of triangular support piece is against on the plate of raking the soil level, and makes the plate of raking the soil level also become certain included angle with level, can the mud of protrusion be pulled back.The push-and-pull process does not all almost have idle work, can improve whole ground efficient greatly.

The good effect of the utility model is: because rabble arm is connected with the hinge of bracing frame through the triangular support piece with the plate of raking the soil level; And leave to stick up and change the gap, produce the tilting force angle, so no matter the plate of raking the soil level rakes the soil level forward or backward; All can accomplish the transmission of power smoothly; Can realize the adjustment of angle again, can make the action of an existing unidirectional useful work realize two-way useful work, be convenient to land readjustment among a small circle.Simple in structure flexible, easy to use, time saving and energy saving.

Description of drawings

Fig. 1 is the utility model overall structure schematic diagram;

Fig. 2 is the utility model connecting portion structure principle chart.

Among the figure, 1, rabble arm; 2, tapered cylinder; 3, circular arc iron bar; 4, bracing frame; 5, triangular support piece; 6, the plate of raking the soil level.

Embodiment

Shown in Fig. 1 and Fig. 2; Utility model is made up of rabble arm 1, tapered cylinder 2, circular arc iron bar 3, bracing frame 4, the triangular support piece plate 6 of raking the soil level; Front end at rabble arm 1 is fixed with tapered cylinder 2, and tapered cylinder 2 is provided with circular arc iron bar 3, and the top of circular arc iron bar 3 is provided with triangular support piece 5; Triangular support piece 5 is an isosceles triangle, and drift angle is 30 degree; Two U type groove bracing frames 4 evenly distribute and rake the soil level on the plate 6, and triangular support piece 5 is connected with bracing frame 4 hinges can stick up commentaries on classics, and the U type bottom land of the base of triangular support piece 5 and bracing frame 9 leaves the gap of 0.2 ~ 1.0cm.Bracing frame 4 passes to rake the soil level plate 6 with the power of rabble arm 1 through triangular support piece 5 as load transfer device, and the plate 6 of when raking the soil level can reasonably stick up commentaries on classics in the push-and-pull process, makes the power of rabble arm 1 be decomposed into the component of horizontal tilt, the moving forward and backward of the plate 6 of being convenient to rake the soil level.

Claims

One kind can before and after the rake of raking the soil level that uses of bi-directional push-pull; Comprise rabble arm, the plate of raking the soil level, it is characterized in that: the front end at rabble arm is fixed with the triangular support piece, two U type groove bracing frames evenly distribute on the plate of raking the soil level; The triangular support piece is connected with the bracing frame hinge; The triangular support piece is an equiangular triangle, and drift angle is 30 degree, and the U type bottom land of the base of triangular support piece and bracing frame leaves the gap of 0.2 ~ 1.0cm.
